摘要
应用极点或排序法及树状图解法对鼠类组成做了类型研究，从空间结构上阐述了群落结构的组成，为鼠类害区及鼠害类型的划分提供了理论依据．
In this paper with the limit-arranging method and the tree-like graphic method we've studied the grouping types of mice,and explained the group structures from the space structure. Thus we' ve put forward the theoretical basis for the division of mouse -damaging distribution ranges and types.
